     View Summary

    Chromium adsorption from the aqueous phase was evaluated using Mongolian sheep wool as a biosorbent. The wool was chemically treated with sodium sulfide to enhance the adsorption capacity. The surface of the wool was analyzed by SEM. EDX and FTIR were also used for the analysis of differences in the wool after chromium adsorption. Chromium was detected in the wool after adsorption by EDX analysis. FTIR data indicated the intensity change in amide A and amide I, which shows chromium may be adsorbed to the amino and carboxyl groups of the wool. The sodium sulfide treated wool showed better adsorption capacity of chromium(III) than the untreated wool. In the case of chromium(III), the adsorption amount increased with the pH increased, while for chromium(VI), the adsorption value increased with the pH decreased. Kinetic analysis of the adsorption indicated that the removal of chromium followed pseudo-second order kinetic model for the whole contact time range. Langmuir isotherm model was used for the analysis of adsorption equilibrium and the adsorption followed well Langmuir isotherm. This study demonstrates the sodium sulfide treated wool is an effective and low-cost biosorbent for heavy metal adsorption.

     View Summary

    For the microcapsules preparation process, the mechanism is estimated by structure reformation during the preparation process since diameter and wall thickness drastically changed. Microstructures are recently studied by machine learning techniques. The Hough transformation algorithm is used by other researchers for the preparation of the microcapsules but it is difficult to determine the mechanism by using only a diameter change of the microcapsules. Therefore, one additional way to establish the mechanism is the analysis of the formation of the microcapsule structure. In this study, The Hough transformation algorithm was used for the image segmentation, the simple feature extractions were checked and the support vector machine and the k-nearest neighbors algorithm were used as classifiers in order to analyze the structure of the microcapsules which were prepared by solvent evaporation method from a solid in oil in water, S/O/W, emulsion system. The structural distribution was analyzed by the developed detection method. The microcapsules had a specific structural distribution which are monocore, multicore, and other aggregated structures. The structural distribution was changed by the preparation condition. The monocore structure was dominant by increasing in the amount of water soluble solid particles added in the organic phase.

     View Summary

    Au(III) and Cu(II) adsorption from aqueous solution were carried out using sheep wools with chemical treatments, by NaOH, Na#D2#DRS, NaHSO#D3#DR, and NaBH#D4#DR aqueous solution. The fibrous wool was transformed into a film like structures after the chemical treatment using Na#D2#DRS. The sheep wool and the chemically treated sheep wool adsorbed selectively Au(III) from Au-Cu binary aqueous solution and the presence of copper ion had no effect on the Au(III) adsorption. Au(III) adsorbed substantially at low pH range. The kinetic experimental data fitted well with the pseudo-second-order kinetic model and the adsorption amount of Au(III) increased with time and reached a plateau after 12 h. The kinetic analysis suggests that rate determining step of Au adsorption would be chemisorption due to the formation of a monolayer on the wool surface. Sheep wool is a low cost, eco-friendly material, and has a high capacity of adsorption, and could be used as a biosorbent for precious and heavy metals by modification of appropriate chemical treatment.

     View Summary

    This study aimed to facilitate efficient arsenic detoxification by inducing the microbial methylation of inorganic arsenic. Recombinant Escherichia coli strains K63 and KC42 were transformed to overexpress arsenic methyltransferase, and the methylation of inorganic arsenic was evaluated using the enzyme extracted from these strains. To ensure continuous reactions by maintaining enzymatic activity, the extracted enzyme was immobilized in microcapsules (MC) to catalyze the methylation of inorganic arsenic. The total yield of methylated organic arsenic compounds in strain K63 was 32.9% (after 2 h of incubation at pH 7.0 and 35°C), of which trimethyl arsenic compounds (TMAC) accounted for 8.3%. The total yield in strain KC42 was 35.9% (after 2 h of incubation at pH 6.5 and 35°C), of which TMAC accounted for 10.8%. When arsenic was methylated using MC prepared with the crude enzyme solution, the total yield of methylated organic arsenic compounds was 12.6% and 5.7% in strains K63 and KC42, respectively. The residual enzymatic activity was calculated to be 53.1 % and 48.8% in strains K63 and KC42, respectively. Future studies should aim to increase the residual enzymatic activity, thus elevating the yield of organic arsenic compounds, by optimizing the conditions for enzyme immobilization in MCs. Key words: Detoxification of inorganic arsenic, Arsenic methyltransferase, Enzyme-immobilized microcapsule, Recombinant E. coli, Cellulomonas sp. K63, Bordetella petrU KC42

    Recent studies suggest that our daily diets have not only nutritional function but also anti oxidative ability. Especially, dietary plants are reported to contain variety of antioxidants such as tocopherol, ascorbic acid, carotenoids, flavonoids, and other polyphenols. Although we have reported antioxidative activity of marine algae [I], most customers frequently eat land plants such as vegetables and fruits rather than marine algae. In this study, we studied antioxidative activity of various vegetables, which commonly consumed in Japan, and examined for their antioxidative activities. In addition, the potent antioxidants observed in the green leafy vegetables were evaluated by using spinach leaf.

    Introduction Reversible complex formation of borate and phenylboronate ions with mono- and oligosaccharides in aqueous solution is well known. These interactions have been employed in separation and detection of compounds containing sugar molecules and synthesis of sugar-responsive materials. Equilibrium constants of the complex formation (Kass) between borate group and particular diols in the saccharide molecules vary from 6 to 2000 M-1 for different sugars, suggesting high selectivity of borate interaction with sugars. Recently, some efforts were made to synthesize water-soluble copolymers containing phenylboronic acid, and to study their properties from the viewpoint of application for sugar sensing and responsing materials and lectin-like materials. Interaction of thermoresponsive boronate-containing copolymers with some carbohydrates and polyols was recently studied by us in a comparative way: owing to hydrophilic properties of the associating molecules, their binding to the copolymer led to a shift of its phase transition temperature (Tp), which might be easily quantified [1, 2]. In this study, we investigated to analyze the interaction of thermo responsive boronate-containing copolymers with some carbohydrates using UV spectral measurement.

    Introduction The nano materials have excellent properties that differ from that of bulk or macro scale. To utilize the nano materials over the long term, it is necessary to avoid the nano materials from the exposure to the environment. Therefore, coating technique of nano materials with retaining the nano-size and highly dispersed condition is need for the nanotechnology. The preparing method of nano materials which uses surfactant aggregate is popular. An anionic surfactant, di-2-ethylhexyl sodium sulfosuccinate (hereafter AOT) forms spherical reverse micelle in a nonpolar organic solvent. The reverse micelles repeat dispersion and coalescence at the very fast rate and exchange the contents of them. Using this property, it is possible to make nano-particles in the reverse micelles. Recently, polymers which show specific properties against the external irritation have attracted much attention. It is known that poly-N-isopropylacrylamide swells in water under the lower critical solution temperature (LCST = 305K), but it shrinks above LCST, because it changes from hydrophilic state to hydrophobic. By this phenomenon, poly-NIPAM has been studied by many researchers in the fields of extraction, adsorption and drug delivery system. However, poly-NIPAM is usually gelatinous, so that there is a little difficulty of handling. In this study, poly-NIPAM is synthesized in the AOT reverse micellar system and coating technology of nano particle using in-situ polymerization is investigated.

    Introduction Immobilization of microorganisms is increasingly applied in biotechnological processes. Currently, the immobilized cells have been extensively used for the production of useful chemicals such as alcohols, amino acids, organic acids, antibiotics, or steroids, and for the degradation of wastewater pollutants. In the immobilization of microorganisms by the encapsulation technique, gel-like materials such as calcium alginate, K-carrageenan, and chitosan are widely used as immobilization matrices, because they have biocompatibility. However, regarding the application of these immobilized cells for long-term reactions, these matrices have a limited stability, in which problems such beads disruption and cells leakage are well-known. Recently, to overcome the problems, there are novel attempts to use synthetic polymers, which have a good mechanical and chemical strength, as immobilization matrices for microorganisms I , 2). In this study, we developed the poly(methyl methacrylate) (PMMA) microcapsule with a single large core, and the immobilization of yeast cells into PMMA microcapsules was researched. In addition, the asymmetric reduction utilizing PMMA microcapsules immobilized· yeast cells was performed in an organic media. The model reaction was adopted as the asymmetric reduction of acetophenone to I-phenylethanol as shown in Fig.l.
